The fighters first met in an opening round matchup on "TUF 11" that Ring won via hotly contested majority decision. However, McGee later won the reality-show tournament when he got a second life with an injury-replacement slot.

UFC 149 takes place July 21 at the 19,000-seat Scotiabank Saddledome in Calgary, Alberta, Canada. UFC featherweight champion Jose Aldo headlines against an opponent to be announced.

UFC 149's main card airs on pay-per-view, and FX and Facebook are expected to carry the prelims. It's not clear where McGee vs. Ring will end up on the lineup.
